Abstract
A disc drive device for driving a disc accommodated in a cartridge comprises: a magnetic head; a magnetic head supporting member for supporting the magnetic head to contact the disc and to be separated from the disc; a lifting plate configured to lift the magnetic head supporting member; and moving means for moving the lifting plate in a direction parallel to a surface of the disc, in which the moving means moves the lifting plate in the parallel direction until the lifting plate abuts the magnetic head supporting member, and further moves the lifting plate in the parallel direction with the lifting plate abutting the magnetic head supporting member so that the lifting plate lifts the magnetic head supporting member up to separate the magnetic head from the disc.
